IMPROVEMENT IN COTTON-SCRAPERS.

Specification forming part of Letters Patent No. 2l.667, date O tober185 To all whom it may concern:

Be it known that I, G. A. GAINES, of Watson, in the county of Marshalland State of Mississippi have invented anew and Improved BlockCotton-Scraper; and I do hereby declare that the following is a full andexact description thereof, reference being bad to the accompanyingdrawings, making part of this specification- Figure 1 being an elevationshowing the right-hand side of the scraper; Fig. 2, an elevation of theopposite side thereof; Fig. 3, a rear elevation thereof, the rear endbeing raised a little in order to show the bottom of the scraper; Fig.4, view of the bottom thereof.

Like letters designate corresponding parts in all the figures.

I make use of a block, A, to which are secured handles B B and a beam,0, nearly as usual for such implements, the beam being secured andbraced to the blork by a bolt, a, passing obliquely downward andbackward through said beam and block and held by a nut, as representedin the drawings. The mold-board or scraper D is shaped and arranged asusual, at single bolt, 1), securing it to the block.

My invention consists in the peculiar shape and arrangement of thebottom E of the block, as follows: Instead of forming a plane surface intheordinary manner, the side and rearedges, c, d, and f, only are in aplane composing the surface which tests on the ground. Fr omthese edgesinward and forward to the edge 9, next to the mold-board, the bottom ismade hollow or concave, the depth of said concavity increasing as itapproaches the front edge, g, and the greatest depth being in the middlethereof. The depth of the concavity is indicated by red lines in Figs. 3and 4. This construction prevents the niold-board from being thrown outits furrow when passing over any kind of impedimentsuch as small stones,roots, &c.- as is the case with ordinary scrapers, so that the scraperpasses more smoothly and evenly over the ground, thereby doing muchbetter work and being much more easily held and guided.

The bottom may be covered by a thin metallic plate, E, as represented inthe drawings, secured to said block by screws or in any other convenientmanner, to protect the block from wear; but this is not essential andmight be dispensed with, although it adds durability to the implement.

What I claim as my invention, and desire to secure by Letters Patent,is-- Giving a hollow or concave form to the bottom E of the block fromthe rear and side edges inward and forward to the mold board or scraperD, substantially in the manner and for the purpose herein specified.

In witness that the above is a true specification of my improved blockcotton-scraper I hereunto set my hand this 9th day of July, 1858.
